Logic Pro 9Logic/Mackie Control Behaving Erratically in Logic 9?

New Member

I was wondering if anyone else was having trouble with their Logic or Mackie Controls, or if anyone might be able to spot what it is that might be causing me trouble.

The shuttle on my LC has suddenly started behaving crazily. If I rotate it just one notch, it jumps ahead 60-something bars. Another notch and it jumps ahead to the end of the session... etc. etc. Moving it back, it seems to get caught on bar 4.

Is there a preference file that's gone corrupt or something? Anyone else have any similar problems?

(Note, that it's not the hardware either--I have both a Logic AND Mackie control, and they're both doing this.)

Actually, it is worth leaving it stand, deleting prefs is often the solution - as you have illustrated. It would be interesting to be able to fathom just what can cause a pref file to get in the state where it seems to result in such behaviour.

For some reason they have chosen to save Logic prefs on exit of the application, instead of just when you close prefpanel. Should logic perhaps not exit completely gracefully things can really go awry, though I imagine some of the corruption also occurs when saving a heavy project while closing the app. At least that's been my experience, and carefully saving then closing a project before closing Logic seems to have made the issue more rarified...
